Description

  The present invention relates to an information communication terminal, and more particularly to processing for displaying a received mail.

  When checking received mail on a mobile phone, open the received mail folder, display a list of senders of the received mail, operate the cursor with the arrow keys, and select one of the mails The mail text is displayed by executing an operation of pressing the enter button for displaying. At this time, the e-mail is treated as a read e-mail as it is viewed by the user. When there is an unread mail that has not been read, an icon for notifying that there is an unread mail is displayed on the mobile phone.

As a technique related to mail list display, there is one described in Patent Document 1 below. Patent Document 1 discloses a mobile phone that displays together the sender information of a mail with a subject selected from the list when the subject of the mail is displayed in a list.
JP 2002-366589 A

  By the way, in recent mobile phones, when a list of received mails is displayed, a cursor is operated with a direction key, and a text of a mail selected by the cursor is previewed. When the cursor is selected, the display is reversed in which the black and white of the character is reversed, or the cursor is simply an arrow, for example. The preview display is to display the received mail together with the list of received mails, for example, for two lines from the top of the body of the mail in order to alert the user of the contents of the received mail selected by the cursor. With the preview display, the user can easily confirm the contents of the mail or sense the contents. In the preview display, since the display area is limited to display with the received mail list, the entire mail text may not be confirmed at the preview display stage, so the mail remains unread. Is desirable.

  However, in the case of a mobile device such as a mobile phone, short mails are often exchanged because long mails are difficult to read and read, and the limited display area may be sufficient. In this case, the operation for setting the above-mentioned mail as read becomes complicated for the user. For example, the user who has confirmed the content in the preview display returns the mobile phone to the standby screen without performing the text display operation. At this time, even though the content of the email is confirmed in the preview display, the email is not handled as read, so an unread email icon is displayed, and the user may have received another email. There may be a situation where you check your email again. In order to prevent this situation, an operation for displaying the mail text must be performed. However, this operation is troublesome for a user who can confirm the content of the mail in the preview display.

  Accordingly, an object of the present invention is to provide an information communication terminal that can eliminate the above complexity.

  In order to solve the above-mentioned problem, the present invention is an information communication terminal that displays a list of received mails and at least a part of the text of the mail in a predetermined display area. Storage means for storing together with unread / read information indicating whether or not the received mail has been browsed, a determination means for determining whether or not the entire text of the received mail is displayed in the predetermined display area, and the determination means Updating means for updating unread / read information relating to the received mail in the storage means to information indicating that the received mail has been browsed when it is determined that the entire text of the received mail is displayed. It is characterized by providing.

  With the configuration as described above, an email in which the entire body of the received email is displayed on the preview screen can be treated as read. As a result, for a mail whose contents can be confirmed once in a predetermined area, that is, in the preview display field, the mail can be treated as read, and a complicated operation for marking the mail as read Is no longer required. In the present specification, a predetermined area corresponding to a part of the display screen is referred to as a preview display field, and displaying a list of received mail and at least a part of the body of the mail in the preview display field is referred to as a preview display. Call it.

Further, the information communication terminal further includes a selection receiving unit that receives a selection operation for selecting one mail from the received mail by a cursor operation, and one mail that is selected by the selection receiving unit. Preview display means for displaying the text as much as possible in the predetermined display area from its head may be provided.
Thereby, the information communication terminal can display a preview of at least a part of the mail text selected by the cursor operation by the user.

In addition, the update unit may be configured such that when a predetermined time elapses after one mail is selected by the selection receiving unit and a part or all of the text of the one mail is displayed in the predetermined display area, An update may be performed.
As a result, the information communication terminal determines whether or not the entire body of the received mail has been previewed when a predetermined time, for example, 5 seconds elapses after the received mail is displayed as a preview. Since the read information is updated to read, the cursor moves at high speed, and only a preview is displayed for a moment. The user has not confirmed the content of the mail but the unread / read information of the unread mail. Can be prevented from being read.

  In addition, the information communication terminal further includes a display receiving unit that receives a display operation for displaying the text of one mail selected by the selection receiving unit without displaying a list of received mails. A full text display means for displaying the full text of one received mail selected by the display accepting means, and the updating means accepts the selection of one received mail at the display accepting means and When the display means displays the text, the unread / read information of the one received mail in the storage means may be updated to information indicating that the received mail has been browsed.

This enables sharing of unread / read information when an operation for reading the mail text is performed without displaying a list of received mail and unread / read information when a preview is displayed. When the full text of the mail is displayed on either one, the mail can be read.
In addition, the updating unit may update the information indicating read only when the unread / read information stored in the storage unit of the received mail is information indicating unread.

Thereby, the unread / read information of the information communication terminal is not always updated, but is updated only when the unread / read information is unread.
Further, the determination means compares the number of characters of the text of the received mail with the number of characters that can be displayed in the predetermined display area, and if the number of characters of the text is less than or equal to the number of characters that can be displayed, the received mail It may be determined that all of the body text is displayed in the predetermined display area.

Thereby, the information communication terminal can determine whether or not the full text of the mail text can be displayed in the preview display field by counting the number of characters of the mail text.
In addition, the information communication terminal further stores a font storage unit that stores a plurality of character fonts together with the size of each character of each font, and the determination unit includes the font stored in the font storage unit. It may be determined whether or not the entire text of the received mail is displayed in the predetermined display area based on the character sizes of the fonts of characters used for display in the predetermined display area.

  As a result, the information communication terminal can determine whether or not the full text of the mail text can be displayed in the preview display field according to the stored and usable fonts. Although the size of one character may differ depending on the font, the information communication terminal can determine whether or not the full text of the mail body can be displayed corresponding to various fonts.

  In addition, when the number of characters in the text of the received mail is one more than the number of characters displayed in the predetermined display area, the determination unit determines whether the one more character is a punctuation mark, and the determination If it is determined by the means that the one more character is a punctuation mark, the received mail indicates unread / read information regarding the received mail in the storage means even if the entire text is not displayed exceptionally. It is good also as updating to the information which shows having browsed.

As a result, when only the punctuation mark protrudes from the preview display field, the information communication terminal can read the mail as if the user read the entire text of the mail. As a user, it is meaningless and complicated to perform an operation of displaying the mail text in order to confirm only the punctuation mark. However, this configuration can eliminate the complexity.
The determination unit may further detect the number of characters of the received mail based on a position where the line feed code is included when the received mail contains a line feed code.

This makes it possible for the information communication terminal to count the number of characters in the email body, taking into account the line feed code, and even if the number of characters falls within the preview display field, there is a line feed code that cannot be displayed. Despite this, it is possible to prevent the situation where the mail is read.
In addition, the information communication terminal further changes the size of characters displayed in the predetermined display area when the determination unit determines that the number of characters in the body is larger than the number of characters that can be displayed. Then, it may be provided with change display means for determining whether or not the full text of the received mail can be displayed, and changing the character size and displaying it in the predetermined display area if possible.

As a result, even if the information communication terminal cannot display the full text of the mail text in the current text size but can display it by reducing the text size, the text can be previewed by changing the text size. As a result, the user does not have to perform an operation for reading the body of the mail.
The information communication terminal may further comprise an unread icon display means for displaying an icon indicating unread on the standby screen when the unread / read information of the received mail is information indicating unread.

  Thereby, when there is an unread mail, the information communication terminal can notify the user that there is an unread mail by displaying it with an icon or the like. On the contrary, in the preview display, when the entire text of the mail is displayed and the unread / read information is read, the icon indicating unread is not displayed, so that the user has viewed all the mail. It will be possible to judge.

  In addition, a mail reading method in a mobile phone that displays, together with a list of received mails, at least a part of a text of a mail selected from the list with a cursor in a predetermined display area, and receiving a mail The determination step for determining whether or not the entire text of the received mail is displayed in the predetermined display area, and when it is determined in the determination step that the entire text of the received mail is displayed, the received mail is An update step of updating unread / read information indicating whether or not the received mail has been browsed to information indicating that the received mail has been browsed may be included.

  Alternatively, in a mobile phone that displays a list of received mail and at least a part of the text of the mail selected by the cursor from the list in a predetermined display area, the computer of the mobile phone reads the received mail as read A mail read program showing a processing procedure, wherein the processing procedure includes a reception step of receiving a mail, a determination step of determining whether or not the entire text of the received mail is displayed in the predetermined display area, In the determination step, when it is determined that the entire text of the received mail is displayed, unread / read information indicating whether the received mail has been browsed is changed to information indicating that the received mail has been browsed. And an update step for updating.

  When the information communication terminal executes this method, or when the computer mounted on the information communication terminal reads and executes this program, the information communication terminal determines whether or not all the mail text has been previewed. If all the mail text is displayed as a preview, the read processing of the mail can be executed. Therefore, the user does not have to perform a special operation for browsing the text of the mail.

Hereinafter, a mobile phone which is an embodiment of an information communication terminal according to the present invention will be described with reference to the drawings.

In addition, when the operation body 120 is operated to display the mail body of one mail by the selection operation by the user, and the mail body is displayed on the display unit 140, the unread / read information of the displayed mail is not read. If it is the information indicating, it also has a function of updating to information indicating the read.
<Data>
FIG. 2 shows a received mail 151 a that is an example of a list of received mails 151 stored in the storage unit 150. As shown in the figure, in the storage unit 140, a mail number field 201, a sender field 202 of received mail, a mail text field 203, and an unread / read information field 204 are stored in association with each other. . Here, only these pieces of information are displayed, but other information may also be associated with the e-mail address and the reception date and time.

In the mail number column 201, information of numbers assigned for the convenience of the mobile phone 100 to distinguish each mail is written.
In the sender column 202, information indicating the person or company that sent the mail is written. In the mail text column 203, information on the text of the mail written in the mail is written.

In the unread / read information column 204, information indicating whether or not the mail has been browsed by the user is written. Here, “read” or “unread” is shown for easy understanding. Actually, on the computer of the mobile phone, “read” is stored as “1” and unread as “0”.
For example, the sender of the mail number “001” is “Tsukanishi”, and the mail text is 13 characters without a line feed code, “Because I bought it and bought it”. The unread / read information of this mail is unread in FIG.

In addition, the sender of the mail number “002” is “Yasuoka Rin”, and the mail text is “10:00 in front of the station. Don't be late?” In FIG. 2, the unread / read information is Unread. The body of this mail has a line feed code after the 8th character, and is composed of 2 lines. The 1st line has 8 characters and the 2nd line has 6 characters.
Further, the sender of the mail number “003” is “Haruko Teramura”, and the mail text is “Ohayo (^ o ^) / Enjoy? Later”. In FIG. Unread / read information is unread. The body of this email contains emoticons, and the emoticon portion is written in half-width characters, and two characters are equivalent to one full-width character. In the body of this e-mail, a line feed code is inserted after the sixth character in full-width conversion and after the third character in the second row, and the first line has 6 characters in full-width conversion. The third line has 3 characters, the third line has 5 characters, and a total of 14 characters.

For the mail numbers “004” and “005”, the unread / read information is “read”.
FIG. 3 shows an example of a display screen in preview display. FIG. 3A is an example of a display screen that displays a preview of the mail text of the mail number 002 together with a list created based on the mail list of FIG. FIG. 3B is an example of a display screen in a state where the text of the mail number 003 is displayed as a preview by a user operation next from the state of FIG.

In FIG. 3A, the line of the mail number 002 is highlighted so that it can be seen that the mail number 002 is selected, and the text is displayed in the preview display field 301a. In the case of the mail number 002, the text is contained in the preview display field 301a.
On the other hand, in FIG. 3B, the line of the mail number 003 is highlighted so that it can be seen that the mail number 003 is selected, and the two lines from the beginning of the body are displayed in the preview display field 301b. Are listed. However, not all the mail text of the mail number 003 is displayed.

  As can be seen from the change from FIG. 3 (a) to FIG. 3 (b), in FIG. 3 (a), the unread mail 002 is displayed in an unread state because the entire text is displayed as a preview. Since the mail has been read, the unread mail icon is not displayed in FIG. This icon display update process is performed after the cursor is moved in a state where the list of received mails is displayed.

Here, the preview display field will be described. The preview display field can display the mail text for only two lines. The first line can display up to 8 full-pitch characters, and the second line can display up to 9 full-pitch characters.
FIG. 4 shows the changed received mail 151b from the received mail 151a shown in FIG. 2 through the preview display as shown in FIGS. 3 (a) and 3 (b).

As shown in FIGS. 3A and 3B, the texts of the mails with the mail numbers 001, 002, and 003 are displayed as previews. With the mail numbers 001 and 002, all of the mail texts are previewed. Although the text was stored in the column, the entire text of the mail with the mail number 003 did not fit in the preview display field.
Therefore, the determination unit 161 notifies the update unit 162 of the full text display information only for the mail numbers 001 and 002. The update unit 162 changes the mail number 001 and 002 flag from “unread” to “read”. As a result, the received mail 151a is updated to the received mail 151b.

FIG. 5 shows an example of display using unread / read information. FIG. 5A shows an example of a standby screen when the received mail is unread, and FIG. 5B shows an example of the standby screen when the received mail is already read.
FIG. 5A shows an example of a standby screen when the received mail is unread, and an unread icon 501 is displayed as shown in FIG. This is displayed when there is unread information in the mail list in the storage unit 140.

On the other hand, as shown in FIG. 5B, when there is no unread information and all are read, the unread icon 501 shown in FIG. 5A is not displayed.
<Operation>
Next, the operation of the mobile phone 100 when the mail is already read in the present embodiment will be described with reference to the flowchart shown in FIG. The description of this operation will be described from the state in which the mobile phone 100 displays the mail list and the preview display screen as shown in FIG.

  First, the control unit 160 of the mobile phone 100 determines whether or not two seconds have passed since the text of the mail that is highlighted and selected is displayed in the preview display field (step S601). This is determined based on whether or not a cursor operation has been performed by the user during that time after the mobile phone 100 has executed the preview display output. If the preview display of the text of the selected mail has not passed 2 seconds (NO in step S601), it waits for 2 seconds to pass, or if another mail is newly selected, the first Then start again. The reason for determining whether or not two seconds have elapsed is to prevent the mail from being read even though the cursor has simply moved and the mail has been selected and the mail text has not been confirmed.

  If two seconds have passed since the preview display of the text of the selected mail is started (YES in step S601), if there is a line feed code at the end of the mail text, the line feed code is removed. (Step S603). However, it is not actually removed, but is performed only to determine whether or not all the mail text is preview-displayed in the present invention. This is because some emails have a new line code at the end, and they do not have to be confirmed by the user, so there is no need to display a preview. This is a process to be executed to make a read.

  With the last line feed code removed from the mail body, the determination unit 161 determines whether there is a line feed code in the mail body (step S605). The presence or absence of a line feed code will be briefly described. The storage unit 150 stores a code for identifying a line feed code in advance, and determines whether there is a code that matches the code in the mail body.

When there is a line feed code in the mail body (YES in step S605), the determination unit 161 determines whether there are two or more line feed codes (step S607).
When there are not two or more line feed codes, that is, when there is one (step S607: NO), the determination unit 161 determines whether the line feed code is after the ninth character of the mail (step S609). If not after the ninth character (NO in step S609), the determination unit 161 determines whether the number of characters described after the line feed code is within nine characters (step S611).

  When the number of characters described after the line feed code is 9 characters or less (YES in step S611), the determination unit 161 displays a preview of the entire text of the selected mail on the update unit 162. Notify that. In response to the notification, the updating unit 162 updates the read mail 151 of the storage unit 150 to read when the unread / read information of the mail is unread (step S613).

  If the number of characters after the line feed code is 10 and the 10th character is not a punctuation mark (NO in step S612), the determination unit 161 has 10 characters after the line feed code, and It is determined whether the tenth character is a punctuation point (step S612). If the tenth character is a punctuation mark (YES in step S612), the determination unit 161 notifies the update unit 162 that all the text of the selected mail has been previewed. In response to the notification, the updating unit 162 updates the read mail 151 of the storage unit 150 to read when the unread / read information of the mail is unread (step S613).

Then, when the mail list display end instruction is received from the user, the process ends. When the direction key is pressed and another mail is selected, the processing shown in this flowchart is performed from the beginning for the mail.
If there are two or more line feed codes (YES in step S607), if there is one line feed code and the line feed code is after the ninth character from the beginning of the mail body (YES in step S609), the line feed code is 1. If the number of characters after the line feed code is 10 and the 10th character is not a punctuation mark (NO in step S612), the mail is not read, and the mail is unread / read information. Exits unread.

In step S605, when there is no line feed code in the mail body (NO in step S605), the determination unit 161 determines whether the number of characters in the mail body is 17 or less (step S606).
If the number of characters in the mail text is not 17 characters or less (NO in step S606), the determination unit 162 determines whether the mail text is 18 characters and the 18th character is a punctuation mark (step S608). ).

  When the number of characters in the mail body is 17 characters or less (YES in step S606), and when the number of characters in the mail body is 18 characters and the 18th character is a punctuation (YES in step S608), the determination unit 161 Notifies the update unit 162 that the entire text of the selected mail has been previewed. In response to the notification, the updating unit 162 updates the read mail 151 of the storage unit 150 to read when the unread / read information of the mail is unread (step S613).

Then, when the mail list display end instruction is received from the user, the process ends. When the direction key is pressed and another mail is selected, the processing shown in this flowchart is performed from the beginning for the mail.
If the mail text is not within 17 characters (NO in step S606), and if the text is 18 characters and the 18th character is not a punctuation (NO in step S608), the mail is already read. And the process ends with the unread / read information remaining unread for the mail.

The above is the read processing in the preview display in the mobile phone 100 according to the present invention.
<Supplement>
Although the mobile phone according to the present invention has been described based on the above embodiment, the embodiment of the present invention is of course not limited thereto. The modifications will be described below.
(1) The present invention may be a method of reading a mail in the mobile phone shown in the above embodiment, or a program that is read and executed by a computer of the mobile phone in order to realize the method. There may be.
(2) In the above embodiment, the font and character size are not particularly described, and only the case of full-width display or half-width display is considered, and it is determined whether or not the entire mail text is displayed in the preview display field. Went. However, the font of characters displayed in the preview display field may be changed according to the user's preference.

The mobile phone according to the present invention may correspond to a plurality of fonts as described above, and may be configured to determine whether the body of the mail fits in the preview display field according to each font.
In this case, the mobile phone previously lists various character fonts in the storage unit 140, and a list showing how much space the character occupies in the preview display field in each font as shown in FIG. Need to hold.

As shown in FIG. 7, the font table 700 includes a font field 701, a character size 702, and a preview display area occupied character count 703.
The font column 701 describes the names of fonts for identifying various fonts.
A character size 702 indicates the size of the character when displayed in the font. Here, the character sizes 702 and 8 are shown. Although not shown here, there may be cases other than 12 and 8.

  In the preview display area occupied character count 703, the area that one character in the font occupies in the horizontal direction in the preview display area is indicated by a numerical value. The converted value is shown. Here, “MS Gothic” and “MS Mincho” have full-width and half-width characters, and “Century” has occupied values in uppercase and lowercase letters. In this case, it is necessary to store the value of the area occupied for each character.

Then, when the control unit 160 determines whether or not all of the mail text can fit in the preview display field, the total occupation of the mail text is determined based on the value of the area occupied by each character corresponding to the font being used. A configuration may be adopted in which the determination is made based on whether or not the area is equal to or less than the number of preview display areas.
(3) In the above embodiment, the determination unit merely determines whether or not the character fits in the preview display field with the current character size. However, when the control unit 160 further changes the character size, It may be determined whether it fits in the preview display field.

If the mail text fits in the preview display field with another character size, that is, a character size smaller than the current character size, the character size may be reduced and displayed. In this case, it is necessary to store the value of the occupied area regarding the height in the font table as shown in the modification (2).
FIG. 8 shows a display example of received mail that can be displayed by reducing the character size. When the character size is 12 as shown in FIG. 7 as shown in FIG. 3B, the entire mail text is not described, but by changing the size to 8, FIG. As shown in the figure, the entire mail text is displayed in the preview display field 801.

Then, since all the text of the mail has been displayed in the preview display field 801, the updating unit 162 sets the mail to “read” when the unread / read information of the mail 003 of the received mail 151 is unread.
(4) In the above embodiment, control is performed in consideration of the line feed code as shown in FIG. In addition, the line feed code may be configured as follows.

For example, when there is a line feed code, the determination unit 161 calculates the number of characters displayed so far in the line in which the line feed code is inserted, and sets the remaining number of characters that should have been displayed in that line as the total number of characters. In addition, it is configured to determine whether or not the total number of characters is within 17 characters.
(5) In the above-described embodiment, the processing of unread / read information may be updated to “read” when all the previews are displayed even if already read. However, if it has already been “read” at the preview display stage, it is not necessary to determine that the entire body is preview-displayed.
